What is the dominant religion there?

I don't know for sure, but since it in South America I am guessing Roman Catholicism (RC is dominant in most South American and Central American countries).

In some places the RC churches have permitted a large degree of indigenous pagan religion to get into their rituals. I have to wonder about attempts to "persuade" demons to do anything, which sounds pagan (as though the demons are kinda bad and kinda good). One has to rebuke them in the name of Jesus Christ; persuasion has nothing to do with the matter.
